Chapter 100: Destroyers and Submarines
The aircraft carrier plan was put on the agenda, and Li Guang's original plan to build gunboats was forced to change. Four high-power diesel engines were ordered by the aircraft carrier, and there were no engines, and many aspects of capital and technology, and even the source of naval guns limited Li Guang from building gunboats such as cruisers.
In addition, after establishing the construction of the aircraft carrier-centered fleet, the first thing to consider is the safety of the aircraft carrier. For aircraft carriers, the biggest threat is not battleships, cruisers, but submarines and warplanes. As mentioned earlier, if an aircraft carrier is hand-to-hand combat by a battleship, it will definitely die, and that is the biggest defeat of the fleet commander, and whether Li Guang or anyone else is the commander of the aircraft carrier, this situation will definitely not be allowed.
As a result, Li Guang decided to build anti-aircraft anti-submarine destroyers. In Li Guang's vision, this type of warship was only equipped with anti-aircraft weapons and anti-submarine weapons. But due to the implementation of the aircraft carrier program, this anti-aircraft anti-submarine destroyer lacked suitable dynamics.
The destroyer Pickup could reach a speed of 22 knots with only a 2,500 horsepower diesel engine, but with the same displacement, the power could only reach 30 knots if the power was increased by four times to 10,000 horsepower. If you want to reach thirty-five knots, you need at least 18,000 horsepower. If you want to run at a speed of 40 knots like the Fengfeng-class destroyer of Yuben, it is definitely impossible to have a power of 50,000 horses.
This time, Li Guang did not propose any hybrid power scheme, but the engineers proposed to add two 2,500 hp diesel engines. The reason is very simple, Li Guang asked for twenty-four high-power searchlights to be installed on the battleship.
Originally, an additional 1,200 diesel generators would have been sufficient, but the engineers thought that it would be better to integrate the power system and use diesel engines for power cruise, while also generating electricity. The workload of repairing two 2,500 hp diesel engines is not much more than that of one 1,200 hp diesel engine.
The diesel engine takes into account the cruise, and at least it can increase the endurance of the pickup-class destroyer to 6,000 nautical miles, (the steam turbine is used in combat and needs to carry not much fuel).
The scheme is very good, and even there are many advantages, even the construction will be very fast, "The drawings of the hull are basically the same as the pickup number, and the original design of the pickup truck is what the destroyer looks like in later generations, and it only needs to be changed slightly".
There is no need to consider weapons, the anti-aircraft artillery made by the Naval Resistance Army will be put into production soon, and almost all problems will be solved one by one. The advantages of this battleship are also obvious, due to the addition of two diesel engines and two generators, as well as fifty tons of batteries, the stability of the battleship is slightly strengthened.
Li Guang also has a little knowledge from the movie about air defense operations that can be used very well on this ship - a strong searchlight. With so many batteries, there is no doubt that it is more suitable for the installation and use of strong light searchlights.
The Pickup-class anti-aircraft and anti-submarine destroyer in the design has extremely powerful anti-aircraft guns, twelve 76.2 anti-aircraft guns (ready to be changed to twin guns in the future), twelve 37mm twin-mounted anti-aircraft guns, and twelve 20mm twin-mounted anti-aircraft guns. Twelve 47mm twin anti-aircraft guns. There will be a total of 48 anti-aircraft guns, 96 in the future, and the auxiliary armament will be 12 twin 12.7mm anti-aircraft machine guns. The capabilities of air defense will be extremely powerful. And the anti-submarine armament is eight depth charge projectiles. The torpedo is two quadruple launchers.
All these weapons seem to be extremely complex, but without the four or eight main guns that are most popular on destroyers in the world at this time, the superstructure is not heavy, or even lighter. You must know that a twin-mounted 150mm naval gun weighs about 80 tons in the whole system. And because the pickup-class destroyers are all anti-aircraft guns, they only use one-inch armor enclosed gun emplacements for protection, and do not use turrets.
The weight of one gun emplacement is no more than ten tons, and the weight of a small-caliber gun emplacement is not even five tons. Such an arrangement of the hull will not appear to be top-heavy of a devil battleship, but what worries Li Guang is that there are so many anti-aircraft guns, which are of astonishing value.
This destroyer actually doesn't have many features, just more professional and anti-aircraft and anti-submarine. If anything, it is the use of three groups of twenty-four high-power searchlights.
In terms of cost, due to the hull itself, in addition to the steel plate used is a little thicker than the pickup, more than 300 tons of armor are used, and the increased cost is only more than 100,000 US dollars. But two diesel engines and motor batteries cost $500,000 at once. With the addition of boilers and steam turbines, the final cost of the destroyer will be around $1.5 million, which is a terrifying cost.
And this is not even the possible cost of 96 anti-aircraft guns in the future, you must know that the price of 96 anti-aircraft guns should be around 2 million US dollars according to the current international market.
However, since diesel engines and motors are in stock, the money Li Guang has to spend now is only a few hundred thousand dollars for the hull and several hundred thousand dollars for the engine, and as for the weapons, there is no shadow yet, let alone spending money.
Otherwise, the two newly built warships, plus the cost of the pickup modification, would be a full 10 million dollars. Li Guang really didn't know where to get the money. However, the anti-aircraft and anti-submarine capabilities of this battleship are far superior to those of destroyers of this era, and even the anti-aircraft and anti-submarine equipment of a battleship or aircraft carrier is not as good as this pickup-class destroyer.
The change in plans has caused a series of problems. The Pixiu-class submarine does not have a main engine, and there is no way to continue construction in the future. And if you want to buy diesel engines from Germany, there are many dangers, not only the possibility of being killed by German submarines, but also the possibility of being sunk by British battleships. (There are two, but they are planned by Li Guang as a backup.) )
At present, two medium-sized submarines are under construction, and since a set of 1,200 horsepower diesel engines is occupied by the aircraft carrier, I am afraid that only three can be built in the end. If the diesel engine is in reserve, I am afraid that only two can be built.
In other words, it is possible for the Maritime Resistance Force to have only four or five submarines, which is absolutely unacceptable to Li Guang. However, if the American diesel engine is used, the failure rate and noise also make Li Guang unacceptable.
There were still several years before the war, and it was obviously unwise to tie up the diesel engine in Germany, so Li Guang turned his attention to the small diesel engine he had developed.
There are several projects here in Uruguay that are now progressing in an orderly manner. After the continuous production of twelve units, after six upgrades, the tank chassis has been basically determined and initially matured.
The development of small diesel engines has now also seen the light of day, and two prototypes have been installed on the tank and are in trial operation. In two years, Li Guang spent countless funds and countless efforts to finally develop this diesel engine.
Eight cylinders with 400 horsepower.
This is quite a deviation from the original assumption, but the size is reduced, the rotational speed is greatly increased, and the noise is significantly reduced. But it is a diesel engine used on the battlefield, and the most critical reliable surname has not been fully verified, and can only continue to be improved in practice.
But Li Guang was already in a hurry, and immediately placed an order to manufacture twenty-four diesel engines first. Twelve of them were intended to be used as tank chassis or assault gun chassis. There were also more than 100 tons of alloy armor captured earlier in the warehouse, and Li Guang did not hesitate to use them.
There were only two kinds of alloy armor captured, one was 12.7mm thick and the other was 25.4mm thick, Li Guang ordered, 25.4mm double layer for important parts, and 12.7mm double layer for sides. Compared with the armor of the 97th tank, the defensive capability has doubled. In fact, due to the performance of such cosmetic parameters as the bevel, the defense capability has definitely more than doubled.
Another twelve Li Guang were intended for use on submarines. With the rapid commissioning of the Raccoon mini-submarine, a project was mentioned for construction. The Pixiu III submarine was put into construction.
If there is a similarity between this Pixiu No. 3 and Pixiu No. 1 and Pixiu No. 2, it is only in appearance. The power is only four 400 hp diesel engines, the same as the Fox mini-submarine. The crew consisted of eleven people and was armed with only four torpedo tubes.
The main purpose of this particular submarine is not to fight, but to replenish combat submarines. Inside this submarine was designed a huge oil storage tank. It can store 1,500 tons of diesel. It is possible to refuel the four existing submarines of the Maritime Resistance Force three times, and even if the small submarines that have already been built are added, they can be refueled twice.
With this submarine, the submarine forces of the Maritime Resistance Force will be able to fight outside for a long time. Due to the low configuration in all aspects, the cost of this submarine is not higher than that of the small submarine of the fox.
As for submarine design, new personnel are constantly being added, and the submarine design team headed by Chinese engineer Lippmann has been enriched. The submarine was truly designed and built entirely by the Chinese, combining the advantages of American and German submarines, and adding some sporadic knowledge that Li Guang had gained from later generations, Li Guang had reason to expect this 500-ton small submarine to become the main submarine of the Maritime Resistance Army.
